MACHINE FOR RRODUCING POLKA DOTS, Sic., ON KNIT OR OTHER FABRIC.

SPECIFICATION forming part of Letters Patent No. 647,162, dated April10, 1900. Application iiled December 18, 1899i. Serial No. 740,679. (Nomodel.)

[o [LU whom t may concern:

Be it known that we, HENRY H. SKnviNG- 'roN and WILLIAM L. WHITEHEAD,residing at Philadelphia, in the con nty of Philadelphia and State ofPennsylvania, and HENRY H. HAWTHORNE, residing at Wilmington, in thecounty of New Castle, in the State of Delaware, citizens of the UnitedStates of America, have invented a new and useful Machine for roProducing Polka Dots or other Designs or Figures on Knit or otherFabric, of which the following is a speciiication, reference being hadtherein to the accompanying drawings.

Our invention relates to apparatus for producing polka dots or any otherdesign or iigure on dyed knit or other fabric. Heretofore the polka dotsor other design on knit fabricfor instance, on stockings-were producedby applying by hand-operated stampingdevices '2o wax dots in the shapedesired to the undyed fabric. The latter was thenV dyed in any preferredmanner and the wax removed by heating, washing, duc., of the dyedfabric. Great difficulty is, however, experienced in obtain- 2 5 inggood results with these hand-operated devices, as the dots or otherdesign will not be of such uniform size or distinction as is desirable,and it has' been found that this only can be had when the pressureexerted on the 3o platen applying the wax or other suitable material isat all times the same and the wax or other material is always in thesame liquid state when applied to the goods. With our machine, which ispower-driven, we not only overcome entirely these difficulties, butcheapen the goods, as the machine is capable of turning out five timesthe goods that could be done by the hand-operated devices. Our machineis also adapted to apply a hot dye 4o by heated forms or molds to afabric in such a way that the design is directly printed onto the goodsdesired to be ornamented.

Ourinvention will be more fully understood taken in connection with theaccompanying drawings, forming part hereof, in which- Figure l is afront elevation of our machine embodying our invention, having asprincipal features a movable table supporting the fabric to be operatedupon, a movable platen 5o carrying the heated mold, and a trough forcontaining and heating the liquid or wax to be applied to the fabric.Fig. 2 is a top view of the machine, showing a stocking on the movabletable to be provided with polka dots from pins secured in the platenforming the mold. i Fig. 3 isa cross-section of the machine on the line3 3 of Fig. 2; and Fig. 4 is an end view of the machine, showing themechanism for operating the platen.

Referring now to the drawings for a further description of ourinvention, A is the frame, comprising the sides a, stationary table A',and distance-rods a'. On the frame in journal-boxes are supported themain shaft B, counter-shaft B', and rock-shaft B2. The counter-shaft Bis driven from the main shaft I3, having fast and loose pulleys b ZJ',by gearing b2 b3, and on the counter-shaft lB are secured two sets ofcams C and C. The set of cams C is adapted to reciprocate the table D,held in gnideways d of the frame A, by means of the two-arm levers d,secured to the rockshaft B2, and link d2, connecting the upper arm ofthe levers d with the movable table D.

The lower arm of the lever d is provided with a roller d3, bearing onthe peripheral edge of the cam O, and this roller d3 is kept in contactwith said edge by the spiral spring d4.

The platen E is vertically reciprocated by the set of cams C', alsosecured to the counter-shaft B. On the sides ct of the frame are hingedthe arms e, having the rollers e bearing on the peripheral edges of thecams C', and on the free end of the arms care pivotally attached theadjustable connectingrods c2, the upper ends of which are :mounted tothe sliding blocks e3 and platen E. The connecting-rods e2 are made intwo pieces and may be adjusted in length bythe setscrews e4, Figs. 1 and4.. The lower portion e5 of the rod is bent at aright angle, .as shownat c6, and is threaded to receive the set-screw e4, while the upperportion el is providedwith a stud es, on which the set-screw e4 bears.After the adjustment of the platen with reference to the height of thetable D is made the two portions e5 and e7 are clamped together by meansof the bolt e9.

The platen E is provided on its under face with a mold or designcomposed of pins t', fastened to a metal plate,which is removablyfastened to said platen E in any preferable IOO l trough F, in which thematerial-wax or dye.-

to be applied by the pins t to the goods supported on the table D iscontained. The trough and its contents are kept in a` heated state by asuitable heating appliance, such, for instance, as shown, whichconsists, preferably, of perforated gas-pipes f.

To avoid the clogging of wax or other material on the pins t',constituting the sign or mold of the platen E, a heating appliance F isprovided and comprises a number of perforated gas-pipes f, located atsuitable distances apart between the pins t'. The perforations in thepipes f are in such direction, however, that the small gas-jets do notcontact with the goods G, held on the table D, and to allow thereciprocation of the platen E the supply gas-pipe f2 is connected withthe distributing-pipe f3 by the iiexible connecting-tube f4.

The operation of the machine is as follows: The goods G to be ornamentedare placed on the table D when the same is near the stationary table A',the pinst of the platen E in this position being immersed in thecontents of the trough F. The platen E now rising to its highestposition, the table D, with the goods, moves in the position shown inFig. 3, when the platen E descends sufficiently to make an impression onthe goods, after which it ascends, and the table D moves toward thetable A again, while the platen E descends to again immerse its pins t'into the contents of the trough F.

If it is desirable, the liquid contained in the trough F may be agitatedto prevent the settlement of the ingredients mixed with the wax orcontained in the dye, tbc., and this stirring is accomplished by a rakeR, hinged tothe back of the reciprocating table D and having teeth r,which when the table moves backward and forward scrape along the bottomof the trough and keep the mixture from settling. This rake R, however,is so arranged that it does not interfere with the operation of theplaten E.

It is obvious to those skilled in the art to which our inventionpertains that modifications may be made withoutdeparting from the spiritof our invention, and,

Having thus described the nature and objects of our invention, what weclaim as new, and desire to secure by Letters Patent of the UnitedStates, is-

1. A machine of the kind described comprisingaframe, areciprocatingtable, a platen moving vertically and coming in contact with the saidtable, a trough below the said table and platen, and means for heatingthe said trough and platen, substantially as and for the purposes setforth.
